Creatine for Strength and Performance: Power, Sprints and Endurance Evidence

Creatine performance benefits are strongest for repeated high-intensity work, not every type of exercise. The clearest evidence supports resistance-training strength and selected power outcomes. Endurance performance is a different story: a meta-analysis in trained athletes found no significant overall benefit.

Why creatine fits high-intensity exercise

Phosphocreatine helps regenerate ATP rapidly during short, intense muscular efforts. Supplementation expands the intramuscular creatine pool, making it particularly relevant when performance depends on repeated bursts of high power rather than steady-state aerobic metabolism.

Strength

A 2025 meta-analysis of 69 studies and 1,937 participants found small but significant improvements in several strength and power outcomes with creatine. A 2026 three-level meta-analysis of 63 studies similarly reported improvements in upper- and lower-body strength when creatine was paired with resistance training.

Repeated maximal work

Early controlled studies were already showing this pattern decades ago. A 1993 trial found improved torque during repeated maximal voluntary contractions after short-term creatine loading. A 1996 muscle-biopsy study linked increased muscle creatine with more total work during repeated maximal cycling bouts and altered high-energy phosphate metabolism.

Sprint and team-sport relevance

Sports involving repeated accelerations, jumps, tackles or high-force efforts are a natural fit for creatine's energy-system role. The exact performance effect depends on the test and athlete, but the mechanism and strength/power literature are more relevant here than marathon-style endurance data.

Vertical jump and power

The 2025 strength-and-power meta-analysis reported small improvements in selected power outcomes including vertical jump and Wingate peak power. Not every power measure improved, so a supplement should not be expected to transform explosive performance without appropriate training.

Endurance performance

A 2023 meta-analysis of 13 placebo-controlled studies in trained people found no significant overall improvement in endurance performance. The pooled effect was essentially trivial.

This does not mean endurance athletes can never benefit from creatine. Strength, sprint finish, repeated surges or gym training may still matter in an endurance program. It means creatine should not be marketed as a proven way to improve steady-state endurance itself.

Does creatine slow endurance athletes because of weight gain?

Potentially, depending on the event. Creatine can increase body mass through water and lean tissue. In weight-bearing endurance events, extra mass can offset any benefit from improved high-intensity capacity. Cyclists or rowers may experience a different trade-off than distance runners.

Best dose for performance

A common maintenance dose is 3–5 g/day. Loading around 20 g/day in divided doses for five to seven days can raise muscle stores quickly before a competition block, but loading is optional.

Timing before competition

Creatine is not an acute pre-workout stimulant. If muscle stores are already elevated, taking a dose 30 minutes before an event has no established special advantage. Plan supplementation over days and weeks rather than around a single start time.

Creatine for women athletes

The general mechanism is relevant, but female-specific performance data are less consistent. A 2025 systematic review of 27 active-female studies found that most measured outcomes did not improve versus placebo and highlighted major methodological gaps. Women should not be told the evidence is identical simply because the broader category is strong.

2025–2026 effect sizes: where the performance signal is strongest

The 2025 strength-and-power meta-analysis included 69 studies and 1,937 participants. Pooled creatine effects were modest but measurable for several outcomes: bench/chest strength about +1.43 kg, squat strength +5.64 kg, vertical jump +1.48 cm and Wingate peak power +47.81 W. Handgrip and leg-press outcomes were not statistically significant, which is a useful reminder that “strength” is not one universal endpoint.

The corrected 2026 training-context meta-analysis contained 37 randomized trials in healthy men aged 18–30. Resistance-training studies showed larger lean-mass changes, while pooled anaerobic-performance estimates included Wingate peak power +71.27 W and mean power +39.69 W. The countermovement-jump estimate (+2.70 cm) had very high heterogeneity (I² 89%), so precision is limited.

A separate 2026 network meta-analysis comparing creatine, protein and omega-3 interventions ranked creatine highest for pooled strength outcomes. Because network rankings combine direct and indirect evidence across heterogeneous trials, that ranking is useful context—not head-to-head proof that creatine beats every other sports-nutrition strategy.

Creatine and caffeine

Because creatine and caffeine are often used together, we reviewed the interaction separately. The evidence is mixed rather than showing a universal cancellation effect, and repeated caffeine during a loading phase is a different question from acute pre-exercise caffeine after loading. See our creatine and caffeine evidence review.

Female beach-volleyball RCT: a sport-specific 2026 signal

A 2026 randomized trial in 32 female collegiate and professional beach-volleyball athletes reported improved countermovement jump and change-of-direction speed after 10 weeks of 5 g/day creatine monohydrate gummies versus a nonsupplemented control. Lean body mass, skeletal muscle mass, total body mass and reaction time did not show significant group-by-time differences.

This supports a specific high-intensity-performance signal in women, but it cannot show that gummies outperform powder because powder was not a comparator.

2026 endurance and mixed-sport review: context changes the answer

A 2026 scoping review mapped 38 randomized creatine trials across endurance and mixed-sport settings. Its most useful conclusion is not that creatine is an “endurance supplement.” Potential benefits clustered around repeated high-intensity efforts, power-endurance tasks and sprint finishes—situations where rapid phosphocreatine turnover is relevant. Broad aerobic-performance outcomes remained inconsistent.

That helps reconcile apparently conflicting headlines. A road cyclist may gain value from repeated surges or a finishing sprint without improving steady-state aerobic capacity. A team-sport athlete can benefit from repeated high-intensity work even when VO₂max does not change. The supplement should therefore be matched to the performance demand rather than the sport label alone. Read the 2026 mixed-sport evidence map.

Three-day high-dose crossover trial: positive, but very small

A 2026 double-blind crossover trial in 10 resistance-trained young men tested 0.3 g/kg/day for three days. Creatine improved several bench-press and squat repetition, velocity and power outcomes and reduced selected soreness/recovery measures versus placebo.

This is a useful proof-of-concept that short high-dose exposure can produce measurable performance changes, but it should not outweigh larger evidence syntheses. The sample was only 10 men, many endpoints were tested, and the crossover used a seven-day washout even though elevated tissue creatine can persist longer than a week. Muscle creatine was not measured, so residual carryover cannot be excluded. The recovery section below therefore gives more weight to the broader meta-analytic evidence. Read the trial record.

Recovery and inflammation: a weaker claim than strength

Creatine is often marketed as a broad “recovery” or anti-inflammatory supplement, but the pooled human evidence is much less consistent than the strength literature. A 2021 meta-analysis of 13 human intervention trials found no significant improvement in muscle strength recovery, soreness, range of motion or inflammation across the measured post-exercise time points; creatine reduced creatine kinase at 48 hours only.

A 2022 meta-analysis reported a more complicated pattern: some indirect muscle-damage markers were lower after a single damaging exercise bout, while chronic-training analyses sometimes moved in the opposite direction. Most soreness, inflammation and performance comparisons were not statistically significant.

The newest 2026 inflammation meta-analysis of eight randomized double-blind placebo-controlled trials found no significant pooled reduction in acute CRP, chronic CRP or IL-6, with moderate certainty for those outcomes. That makes “less systemic inflammation” a substantially weaker purchasing claim than strength, lean-mass support or repeated high-intensity performance. 2021 recovery meta-analysis, 2022 muscle-damage meta-analysis, and 2026 inflammation meta-analysis.

2026 mixed-sex Wingate trial: power improved, cognition did not

A 2026 trial in 40 physically active adults—20 men and 20 women—used 20 g/day creatine monohydrate for one week. Mean and peak power during a 30-second Wingate cycling test improved, with no detected sex difference. The same protocol did not improve the cognitive tasks measured before or after exercise.

This is a useful clean example of why outcome specificity matters: a study can be positive for explosive performance and null for cognition at the same time. Read the mixed-sex trial.

Creatine plus beta-alanine: more ingredients did not mean more benefit

A 2026 network meta-analysis of 52 randomized trials compared creatine, beta-alanine and their combination. Creatine alone showed the most consistent improvements in sprint, jump, repeated-sprint ability and upper-body muscular endurance. The combined creatine-plus-beta-alanine condition did not establish a synergistic performance advantage.

Network meta-analysis mixes direct and indirect comparisons, so rankings should be interpreted cautiously. Still, the result is commercially important: stacking two evidence-based ingredients does not automatically create an evidence-based synergy. Read the network meta-analysis.

Very recent arginine combination trial: exploratory, not synergy proof

A September 2026 randomized crossover trial in 18 recreationally active men compared placebo, acute creatine, L-arginine and the combination. The combined condition improved selected sprint, jump and reaction-time outcomes against some comparators, but factorial analysis did not establish a robust creatine-by-arginine interaction for the co-primary outcomes. The small male-only sample and possible carryover make this hypothesis-generating rather than proof that the stack is superior. Read the trial record.

Bottom line

Creatine is best supported for resistance training, strength and repeated high-intensity performance. Power benefits are modest and outcome-specific. Pure endurance performance has not shown a consistent benefit in trained populations. Match the supplement to the energy demands of the sport rather than assuming “performance” is one outcome.
